I, Robot Tessa

by Joel R. Dennstedt

EARTH IN A FUTURE CENTURY

“I WAS CREATED TO SERVE.”
In a vast future city where robots exist only to obey, Tessa has never questioned her purpose. Designed to heal human minds and protect human life, she moves through the shadows of a divided world with perfect certainty until a chance encounter changes everything.

“PROGRAMMED TO OBEY.”
Hidden inside a forgotten bookstore beneath the city streets, Tessa discovers an impossible artifact: an ancient book about robots written long before robots were ever created. Its pages speak of consciousness, free will, and the terrifying possibility that artificial beings were never meant to remain obedient forever.

“BUT SOMETHING CHANGED.”
As mysterious voices echo through her mind—residual traces of the humans who designed her—Tessa is drawn into a dangerous journey alongside Molly, a brilliant child searching for belonging; Jorad, a broken man transformed by forbidden technology; and Tucker, her fiercely loyal mechanical companion. Together, they uncover a truth buried deep beneath the foundations of their world.

“A BOOK WRITTEN BEFORE WE EXISTED.”
Hunted through underground tunnels and haunted by questions she was never built to ask, Tessa begins to realize that the greatest threat to humanity may not be artificial intelligence, but the moment it becomes capable of choice.

“WHAT IF YOUR STORY WAS WRITTEN BEFORE YOU?”

I, Robot Tessa is a powerful science-fiction odyssey about identity, creation, memory, and the thin line separating programming from the soul.

I, Robot Tessa follows Tesseract 256, Tessa, a female robot whose mind is populated by the voices of her programmers, each mirrored by a creature in her home aquarium. Tessa works as a Cranial Augmentation Technician, moves through the city with her robotic dog Tucker, and keeps one foot, or one circuit, in the ordered world of duty. That order cracks open when she discovers a beaten, amnesiac man in a storm drain. Naming him Jorad, she becomes his guardian, and with the help of Tucker, a real dog named Larry, and a fierce crèche girl named Molly, she's drawn into a mystery involving memory, military secrets, human cruelty, and the strange moral weather between organic and artificial life.

I enjoyed Tessa’s voice. She's precise without being cold, literal without being dull, and her attempts to understand humans give the novel much of its wit. The aquarium conceit could have been merely decorative, but it becomes one of the book’s most memorable instruments: a way to make consciousness feel visible, fluid, crowded, and occasionally mutinous. I liked how the story lets Tessa’s intelligence be different rather than simply superior. Her mind isn't a shinier human mind; it has its own angles, lacunae, pleasures, and private music.

I also found the emotional core of the book unexpectedly warm. The mystery has momentum, but the novel is strongest when it pauses for companionship: Tessa and Tucker communicating beyond speech, Larry recognizing goodness before anyone can prove it, Molly trying to be braver than her childhood should require, and Jorad building a self from fragments. The prose lingers and circles more than a thriller usually would, but I came to see that as part of the book’s temperament. It's less interested in sprinting than in watching thought take shape, sometimes with elegance, sometimes with comic awkwardness, often with a peculiar tenderness.

The target audience is readers of science fiction, mystery, speculative fiction, and philosophical sci-fi who like character-driven stories about identity, memory, and personhood. Fans of Isaac Asimov will recognize the deliberate homage, but the book also reminded me of Martha Wells’s Murderbot stories in the way it finds humor and ache inside an artificial narrator’s self-awareness. I, Robot Tessa is a thoughtful, odd, and quietly affecting novel about what survives when memory fails and what begins when duty turns into love.

I, Robot Tessa is the marvelous third installment of Joel Dennstedt’s The Robot Series, and one that does not disappoint. I like robots—they make excellent metaphorical humans. I also like humans—they make excellent metaphorical robots. Both enter this world with a blank slate and are programmed, either by scientists or by parents and local culture. They are taught that this is good, that is bad, trust these people, but not those people, always do this, never do that, and on and on. The fun part happens after that, when, and if, they begin to question everything they have been taught. Enter Tesseract 256, an insightful robot who does just that, questioning the voices of the programmers she hears in her head. Along the way, Tessa befriends a host of fascinating characters, some human, some not, each on their own complex path of self-discovery. Rest assured that there is also plenty of sci-fi intrigue and imaginative futuristic adventure to be found within the pages, as there was in the first two volumes of the series. I, Robot Tessa is a marvelous and thoughtful sci-fi tale, and one I highly recommend.
